二、Jenkins与GitLab集成实现自动构建(可忽略)
2.0 安装Git和Maven
# 安装Git
[root@jenkins ~]# yum install -y git
[root@jenkins ~]# git --version
git version 1.8.3.1
# 安装maven,地址: https://archive.apache.org/dist/maven
wget https://archive.apache.org/dist/maven/maven-3/3.8.6/binaries/apache-maven-3.8.6-bin.tar.gz
mkdir /opt/maven
tar xzvf apache-maven-3.8.6-bin.tar.gz -C /opt/maven
vim ~/.bash_profile
# 内容 BEGIN
export M2_HOME=/opt/maven/apache-maven-3.8.6
export PATH=$M2_HOME/bin:$PATH
# 内容 END
source ~/.bash_profile
[root@jenkins ~]# mvn -v
Apache Maven 3.8.6 (84538c9988a25aec085021c365c560670ad80f63)
Maven home: /opt/maven/apache-maven-3.8.6
Java version: 11.0.21, vendor: Oracle Corporation, runtime: /opt/java/jdk-11.0.21
Default locale: zh_CN, platform encoding: UTF-8
OS name: "linux", version: "5.11.12-300.el7.aarch64", arch: "aarch64", family: "unix"
vim /opt/maven/apache-maven-3.8.6/conf/settings.xml
<localRepository>/opt/maven/repo</localRepository>
<mirrors>
<!--<mirror>
<id>maven-default-http-blocker</id>
<mirrorOf>external:http:*</mirrorOf>
<name>Pseudo repository to mirror external repositories initially using HTTP.</name>
<url>http://0.0.0.0/</url>
<blocked>true</blocked>
</mirror>-->
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>
2.1 下载安装Pipeline插件
2.2 Jenkins 安装插件 GitLab Plugin、Maven Integration Plugin
2.3 服务器编写测试脚本
[root@jenkins ~]# echo "echo "hello world"" >demo.sh
[root@jenkins ~]# chmod +x demo.sh
[root@jenkins ~]# ll demo.sh
-rwxr-xr-x. 1 root root 16 1月 13 16:28 demo.sh
2.4 Jenkins创建自由风格项目并填写构建脚本
2.5 配置钩子脚本
# 服务器执行安装openssl
yum install -y openssl
# 生成ssl令牌 -> d22f1292ecf0a36007ab
openssl rand -hex 10
2.6 GitLab创建项目添加钩子脚本
保存报错
解决：Settings → Network → Outbound requests
再次添加hooks
报错
解决
还不行，去掉Jenkins系统设置里的 Enable authentication for ‘/project’ end-point
自动构建成功
三、基于Jenkins、Harbor、GitLab自动部署SpringBoot项目到K8S
3.1 创建项目
3.2 配置Jenkins
参考2.4~2.6配置即可，最终验证钩子返回200 OK
Manage Jenkins → Tools
3.3 配置Harbor
添加用户Jenkins
添加项目
项目添加成员
3.4 Jenkins和K8S Master做免密
# jenkins, 若有可不执行
ssh-keygen -t rsa -P "" -f ~/.ssh/id_rsa
[root@jenkins ~]# cat ~/.ssh/id_rsa
